Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install shopify-theme-core-web-vitals

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent diagnoses slow Shopify theme pages against LCP, CLS and INP, then fixes hero image loading, image delivery and fonts. You get the theme changes and a before-and-after measurement method.
